Vacuum pressure relief modules
Protection of the vacuum pump against excess pressur
Excess and residual pressure in high-pressure systems can damage the vacuum pump. WEH vacuum pressure relief modules effectively protect vacuum pumps against damage due to excess pressure.
Excess pressure is safely & reliably vented into the room or discharged outside.
